Hello... is anyone home??

I have in the past month tried three times to get in touch with MAXX marketing (marketing@maxx-marketing.net). I would like a price on a job I'd want them to do, but I get no response and they act as if they couldn't care less.
Are there any other ones that has come in contact with them?
I really do not understand how they can operate a business without responding to customers mails.
